Lego has stopped a project to make building blocks based on recycled PET bottles. The material causes higher CO2 emissions, the Danish toy manufacturer reports.
Lego had announced in 2021 that it would investigate whether PET bottles could be used for the production of building blocks. Lego now informs the Financial Times that PET bottles would cause higher CO2 emissions.
The company will improve the ecological footprint of ABS, a hard petroleum-based plastic. Tim Brooks, head of sustainability at Lego, says that PET bottles require additional ingredients to make them safe and durable enough, as well as large amounts of energy to process and dry them. “It’s like trying to make a bicycle out of wood instead of steel,” Brooks said.
